Application June 20, 1955, Serial No. 516,554

6 Claims. (Cl. 242-5551) My invention relates in general to roll formpaper products dispensers andin particular to a device vwhich is ofvtheltype shown and described in my Patent No. 2,597 ,602 -issued to meon May 20, 1952.

The principal object of the present invention ris to'provide Va.paper'dispensingidevice which is economical to manufacture, safeto useand durable in operation.

Another object is to providea paper dispenser having spaced a'ngesproviding a tear-off means through `which the paper is drawn and bywhich vit may be conveniently grasped, pulled 'out to desiredlength andthen torn olf.

-A'nother object is to'provide a tear-off `means having va Vtear-offbladevand an adjacent guard flange for effecftively'protectingthe'blade, whereby the userfcannotinjure himself bycontact therewith.

Another object is to provide anraccessible reserve portion of paperafter'the desired portion is removed and y severed fromthe roll.

`A further object is to provide an access recess in the guard flange,whereby the Vreserve portion of paperxmay be readily contacted byl-onehand ofthe user to withdraw'another portion of paper subsequent Vtosevering.l

Another object is to-provide means for supportinglthe 'reserve portionof paper so asy to keep it smooth and straight previous to beingwithdrawn from the device.

Moreover, it has been an object to provide adevice from asingle'pieceofsheet material bent so as to-form a casing havingend tabs at one end`for substantially enclosing the casing and end tabs at the yoppositeend providing an opening suiciently large to insert a roll-ofpaperjendwise for easy refilling.

Another object'is to-provide a dispenser havinga cas- 4ing :formedwith'an inclined bottom for supporting `the Vroll and causing it to rollinto frictional contactwith one of the side walls, whereby the roll ofpaper will be frictiona'lly held in place and therebyobviatethettend'ency for the severed edge to loosely unroll.

Furthermore, the tearing edge'of the blade of Ymy V'device is relievedby havingthe teeth beveled backwardly s'o as to facilitate the tear-olfaction.

'My invention is applicable to various uses and. for the *dispensingofvarious types of paper supplied'from a'roll.

Inf'the drawings, many applications of my'invention are shown; and theabove objects and advantageshave Ikbeen'accomplished'by the device shownin theaccompanying drawings, of which:

.Myldevice comprises. a casing A15 formed of a sheet of .metal 16s'haped.aspshown in Fig. y10, dot and dash lines 20.20, .21, 22, 23,l-24 and 25 representing where bends Vare ito'bergprovided kwhen-formingthe-sheetinto a complete .-casing.

Eachof the end flanges is"forn1edv.withan arcuate end surface 46,;-wherebywhen/foldedas'shown in Fig. l5,anvend openingSO willibe provided. lAtthe opposite end of the sheet"of'material, tabs 51, 52, :53 and '54 are provided lextendingffromportions 35, 32,37 and30, respectively, :eachsend :ange being Aformedwith curved surface -55 of relatively dargeradius'which -forms a loadingopening 56.when-1'the sheet is folded in form as shown `in Figs.'l2.'and 3. "Thexend an'ges-have theirfsideedges cut-atsubstantially.45"7 withthe Ybendflines so-thatl when the.materialisfoldedlin completedform, thejoints between Ethe tabs1wi1lbe'closed. In order,`however,vto provide lforfthe V'threa`ding1offreerend y58 ofthe papervinto the :device1as-thefroll'59 isinserted'ftherein, the edges 60 and .61 of1 theend flanges '51 and 54,respectively, arevso -proportionedand-positioned that an insert-slot 68is provided'between these fllanges Whenthe sheet is folded in 'theformof alcasin'gfas shown clearly in Figs. 2 and 3. The material is soproportionedvthat-when foldedthe f-supportinganges i36-will extendslightly beyond the fedge ofi the cut-offy bla'de 31. The blade is heldin spaced :relation with theflanges preferably by dimples 65Y shown inFig. 7,.'thereby forming a paper dispensing opening 67. The blade isformed on its forward edge with a cutlting surface comprisingtwoserrated portions 62 and 63 .joinedby'a .central straightaunbrokenportion 64. v'Each 65 serrated portion is'formed with V-shaped teeth 69which larepreferably inclined downwardly and outwardlyon their upper.surfacestoward the points so as to present fasharptcutting. edge to thepaper when drawn upwardly into tearing relationzitherewith. The ends ofthe cut-olf blade -31.and ;the outerends,5oi.1he,supporting flanges,3.6V

is withdrawn from the device. As clearly shown in Figs. 6 and 9, thecutting edge is recessed suiciently so that there is no possible dangerof the operators injuring himself when he grasps the Vportion ofmaterial exposed in 4 tear-off blade 76.

In the form of invention shown in Fig. 12, 80 reprev sents a counterunderneath which the roll of paper 81 is supported upon suitablebrackets 82 secured t-o the under side of the counter. The cut-offdevice in this form of invention comprises a cut-off blade 83 suitablycarried by a strip of material 84 carried by the counter 80, and asupporting flange 85 suitably held in spaced relation with the cut-offblade. As clear in both of these figures, the supporting flange extendsbeyond the outer edge of the cut-off blade for protection to theoperator, and an access opening (not shown) is provided as in the formof invention shown in Figs. l-l0.

In Fig. 13, I show a form of spacer adapted for use with the type ofdevices shown in Figs. 11 and '12. In this form, the-supporting flanges90 are each bent upon themselves at their `outer edges thereby forming aspacing member 91 at each end for engagement with the bottom surface ofthe blade 83.

When paper is to be dispensed from the roll 59 in the form of inventionshown in Figs. 1 to 10, inclusive, the portion of the paper exposedopposite the access opening 40 is contacted Iby the fingers of theoperator and is drawn outwardly to dispense the desired amount of paperbeyond the edge of the tear-off blade. When the desired amount of paperhas been dispensed, it is drawn kupwardly and at one side thereof fortearing engagement with one ofthe toothed ends of the cut-off flange,readily Vstart the tearing operation of the paper which is continuedacross the straight portion 64 and completed over the area of thetoothed portion at the opposite end of theV blade. Obviously, when thedevice is loaded, the roll of paper is passed through the chargingopening 56 with the free end thereof engaging the insert slot 68 untillthe roll is completely within the casing, whereupon the roll 59 willlie upon the bottom 35 of the casing with its outer free end disposed inthe space 67 between the supporting ange and the tear-off blade. When inthis position, as clearly shown in Figs. 2 and 3, the front portion ofthe roll will be in frictional contact with the front wall 30, as wellas with the bottom 35, thereby maintaining the roll in the positionoccupied when paper is withdrawn therefrom and keeping the paper frombeing pulled back into the casing when the desired portion has beensevered from the roll.

Dispensing and severing of the heavier papers, such as wrapping papers,parchment papers, kraft papers and the like, by means of the deviceshown in Figs. 11 and 12 is substantially the same as that justdescribed.
